ABSTRACT

BACKGROUND: The short-term effect of ambient air pollution on atopic dermatitis (AD), along with its effect modifiers, has not been fully addressed. OBJECTIVES: To examine the short-term associations between air pollution and AD, and to identify effect modifications by age and season. METHODS: We used the generalized additive model to evaluate the short-term effect of ambient air pollution on daily hospital visits for AD, adjusting for potential confounders. Subgroup analyses were performed to identify potential effect modifications by season and age (< 18 years and ≥ 18 years). RESULTS: A total of 29 972 hospital visits for AD were recorded in Guangzhou, China, from 19 January 2013 to 31 December 2017. Among them, 72·8% were visits by children and 51·4% occurred in the cool season. Acute and delayed effects on AD hospital visits were significant for all air pollutants. Stronger effects were seen in the cool season (approximately 1·7-3·0 times higher than effects in the warm season). Stronger effects were also observed in children (approximately 1·3-1·8 times higher than effects in adults). Sensitivity analyses indicated the results were robust. CONCLUSIONS: Air pollution might be an important trigger for AD in subtropical Guangzhou, China. Children are more vulnerable than adults, and the effects are stronger in the cool season.

ABSTRACT

Little research has focused on suicidality in the era of successful antiretroviral therapy among those engaged in HIV care. We performed a study of 648 clinic patients who completed a psychological and behavioral annual assessment in 2012. Depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9), suicidal ideation was measured by the last item of the scale. Anxiety symptoms were measured using the Generalized Anxiety Disorder-7 questionnaire (GAD-7). HIV biomedical markers were abstracted from medical records. Suicidal ideation was reported among 13% (n = 81) of the sample. Individuals endorsing suicidality were more likely to have unsuppressed viral loads, moderate to severe anxiety symptoms and consider themselves to be homeless (p < 0.01 for all). After adjusting for confounders, homeless individuals and those endorsing moderate to severe anxiety symptoms had higher odds of reporting suicidality. Results suggest basic needs must be met to complement HIV management efforts. Furthermore, better understanding of how psychological distress symptoms are expressed and how to manage them may better inform barriers to HIV management.

ABSTRACT

The role of sexual function and its impact on HIV management have been inadequately evaluated. A cross-sectional study in 2009 of 202 patients with HIV were recruited to examine sexual function and psychosocial/HIV management factors. Analyses assessed the relationship between sexual function, sociodemographic factors, biomedical markers, and depressive symptomology. The M-Estimator compared differences in the means of the HIV, cancer survivors, and the normative cohorts. More than 75% were on combination antiretroviral therapy, of which 70% had suppressed HIV viral loads. Patients with unsuppressed HIV viral loads reported lower rates of arousal. Better overall health was associated with higher rates of overall sexual function, arousal, and interest. Compared to the normative and cancer survivor cohorts, mean sexual function was significantly lower in the HIV-infected cohort in all subscales, except for masturbation. These findings suggest lower sexual function impacts individuals with HIV in ways related to negative biomedical and psychosocial factors.

ABSTRACT

Adverse neighborhood conditions play an important role beyond individual characteristics. There is increasing interest in identifying specific characteristics of the social and built environments adversely affecting health outcomes. Most research has assessed aspects of such exposures via self-reported instruments or census data. Potential threats in the local environment may be subject to short-term changes that can only be measured with more nimble technology. The advent of new technologies may offer new opportunities to obtain geospatial data about neighborhoods that may circumvent the limitations of traditional data sources. This overview describes the utility, validity and reliability of selected emerging technologies to measure neighborhood conditions for public health applications. It also describes next steps for future research and opportunities for interventions. The paper presents an overview of the literature on measurement of the built and social environment in public health (Google Street View, webcams, crowdsourcing, remote sensing, social media, unmanned aerial vehicles, and lifespace) and location-based interventions. Emerging technologies such as Google Street View, social media, drones, webcams, and crowdsourcing may serve as effective and inexpensive tools to measure the ever-changing environment. Georeferenced social media responses may help identify where to target intervention activities, but also to passively evaluate their effectiveness. Future studies should measure exposure across key time points during the life-course as part of the exposome paradigm and integrate various types of data sources to measure environmental contexts. By harnessing these technologies, public health research can not only monitor populations and the environment, but intervene using novel strategies to improve the public health.

ABSTRACT

OBJECTIVES: HIV infection has become a manageable chronic disease as a result of treatment advances. Secondary prevention efforts have proved inadequate to reduce the estimated incidence of new HIV infections. Epidemiological data suggest that geographical clustering of new HIV infections is a common phenomenon, particularly in urban areas among populations of low socioeconomic status. This study aimed to assess the relationship between neighbourhood conditions and HIV management and engagement in high-risk behaviours. METHODS: During routine out-patient HIV clinic visits, 762 individuals from the St Louis metropolitan area completed behavioural assessments in 2008. Biomedical markers were abstracted from their medical records. Multi-level analyses were conducted based on individuals' census tracts. RESULTS: The majority of the sample were male and African American. In the adjusted models, individuals residing in neighbourhoods with higher poverty rates were more likely to have lower CD4 cell counts and be current smokers. In neighbourhoods with higher rates of unemployment, individuals were less likely to have a current antiretroviral prescription. In more racially segregated neighbourhoods, individuals reported more depressive symptoms. CONCLUSIONS: Despite the advances in HIV disease management, neighbourhood characteristics contribute to disparities in HIV care. Interventions that address neighbourhood conditions as barriers to HIV management may provide improved health outcomes.

ABSTRACT

Recent studies support technology-based behavioral interventions for individuals with HIV. This study focused on the use of cell phone and internet technologies among a cohort of 515 HIV-infected individuals. Socio-demographic and clinic data were collected among individuals presenting at an urban Midwestern university HIV clinic in 2007. Regular internet usage occurred more often with males, Caucasians, those who were employed, had higher income, and were more educated. Higher levels of education and income >$10,000 predicted regular usage when controlling for race, employment, and gender. Cell phone ownership was associated with being Caucasian, employed, more educated, and salary >$10,000. Employment was the only predictor of owning a cell phone when controlling for income, race, and education. Individuals who were <40 years of age, employed, and more educated were more likely to know how to text message. Employment and post-high school education predicted knowledge of text messaging, when controlling for age. Disparities among internet, cell phone, and text messaging usage exist among HIV-infected individuals.

ABSTRACT

Individuals with HIV experience fluctuating levels of distress throughout the course of HIV infection. This study was conducted to examine the associations of depressive symptomatology with HIV disease in a cohort of individuals who are engaged in routine medical care. This cross-sectional study examined the prevalence of depressive symptoms that were measured as part of a standard of care behavioral assessment among individuals at an urban HIV clinic in the Midwest. Demographic characteristics, depressive symptoms, and behavioral risk factors were collected. A total of 514 individuals participated in the study, the majority of whom was male and African American. One quarter of the sample endorsed symptoms of other depressive disorder, while 18% (n = 91) endorsed symptoms of major depressive disorder as measured by the Patient Health Questionnaire-9 (PHQ-9). Among those on highly active antiretroviral therapy (HAART), individuals who were unemployed (adjusted odds ratio [AOR] = 2.47, 95% confidence interval [CI] = 1.54, 3.97), had a minor dependent (AOR = 2.17, 95% CI = 1.25, 3.77), or between the ages of 18 and 34 years (AOR = 1.37, CI = 1.03, 1.94) and detectable HIV viral load (AOR = 2.52, 95% CI = 1.22, 5.23) were more likely to report depressive disorder symptoms when controlling for age, gender, race, and education. Nearly 15% of the sample endorsed having suicidal thoughts at least once in the past two weeks. Regardless of HAART prescription, individuals who were unemployed had a higher likelihood of expressing suicidal ideation (AOR = 3.43, 95% CI = 1.66, 7.06). Given the association between depressive symptomatology and poor rates of HIV viral suppression, screening and appropriate interventions for depressive symptoms are warranted in the HIV outpatient setting to improve outcomes.

ABSTRACT

While researchers in many western countries have documented the nature of psychological distress that is commonly present among individuals living with HIV, there has been virtually no research on the same topic among other high prevalence areas of the world, particularly in countries like Kenya. This study sought to document the nature of psychological distress among 397 individuals living with HIV in western Kenya and who were participating in psychosocial support groups in conjunction with their enrollment in HIV-related treatment. Psychological distress was assessed using the Brief Symptom Inventory (BSI), a 53-item self-report psychological inventory that asks individuals to recall symptoms experienced in the prior seven days. The levels of psychological distress in this sample were moderate with a substantial proportion of participants meeting the criteria that suggested a need for further psychiatric evaluation. Findings support the need for further assessments of the range and nature of psychological distress among the diverse communities of countries like Kenya and the need for greater attention to the inclusion of mental health services in the rapidly developing treatment and prevention programs in this region of the world.
